Zoho Interview Experience | Set 22 (Experienced)

Only user-defined functions. No inbuilt functions at all. 
No scanning for inputs, directly assign to vars. 

Level 1: (2 hours - pen & paper) 
1.Solve the equation X power Y with given values. 

Example:
 Input: X=2, Y=-2
 Output: 0.25

2.Find the distance between two given points and round it to the nearest number.

Example:
 Input: (2,4)(4,10)
 Output: 6

3.Count the numbers of characters in the given string treating '$' as escape sequence. If '$' is preceded by '', consider it as normal '$' and not the escape sequence. If '' occurs, treat it as single ''.

Example:
 Input: Hello$World$
 Output: 11

4.Given a 2D matrix, find the sum of all the elements.

Example:
 Input: [1 2 3]
 [4 5 6]
 [7 8 9]
 Output: 45

Level 2: 
Finish one question to get the next type. Total 5 questions. (3 hours - machine round) 
1.Solve the equation (XpowerY/Z!) + (Z/(X!+Z)) with given values of X, Y, Z. X and Z cannot be negative.

Example:
 Input: X=2, Y=3, Z=4
 Output: 1

2.Batman, Spiderman and Superman are going to start a business. The total investment is 1000M$. Anyone can add new investment to their existing investment. They can transfer investments between themselves. The program should be in OOP style and should have a menu for user to do all operations. (Something similar to below example.) 

Constraints:
 a.Total investment should always be 
 equal to or lesser than 1000M$.
 b.Spiderman's investment should never
 exceed Batman's.
 c.Investment cannot go into negative.
 d.Display investments on each update.
Example:
 Input: batman = 300, spiderman = 250,
 superman = 100
 Output:
 batman - 300
 spiderman - 250
 superman - 100
 add 100 into spiderman
 sorry, spiderman cant have more 
 investment than batman add 200 
 to batman
 batman - 500
 spiderman - 250
 superman - 100
 add 500 to superman
 sorry, total investment cant 
 exceed 1000. 

I couldn't get the 3rd question as I ran out of time. Need to complete 3 questions to qualify for next round.
